The 'slave' who claims she had sex with Prince Andrew while under-age is writing a book that threatens to go into forensic detail about her alleged involvement with the Duke of York, MailOnline can reveal today.

She also plans to name American politicians, business executives, foreign presidents and a well-known Prime Minister she claims Jeffrey Epstein forced her to sleep with.

MailOnline understands that Miss Roberts, whose father has claimed she met the Queen, could publish the book this year, which means the scandal shows no sign of abating for the royal family.

Buckingham Palace is said to have conceded the furore 'isn't going to go away' as Prince Andrew is expected to hold crisis talks with the Queen today as he returned to Britain after a luxury holiday with his ex-wife Sarah Ferguson and daughter Eugenie.

The Duke of York was locked inside a £22,000-a-week ski lodge in Verbier for two days after he was accused of abusing the girl ‘procured’ for him by his close friend and convicted paedophile Epstein.

The extraordinary allegation made by Virginia Roberts is part of a US civil case against shamed billionaire Epstein. She claims Prince Andrew had sex with her when she was 17 – a minor under US law – and employed as a ‘sex slave’ by Epstein.

The fifth in line to the throne slept with Miss Roberts at an orgy with other under-age girls on Epstein’s private Caribbean island, as well as in a private house in London and in Epstein’s New York mansion, according to the court papers.

The prince – who looked sombre as he left his luxury £22,000-a-week Swiss ski chalet yesterday – is today expected to meet with his most senior aides and lawyers in his mansion close to Windsor Castle.

It is also understood he will reassure his mother at the earliest possible opportunity that the claims he faces are false.

But if Miss Roberts does publish a tell-all book, which expands on the claims she made in court papers, it could be a major embarrassment to Prince Andrew and the Royal Family.

It could also lead to the naming of other high profile people and could lead to further police investigations and to some prosecutions.

MailOnline was told today by one of Ms Roberts' closest friends that she had started planning the book at least a year ago, before she and her husband Robert decided to move from Australia to the United States, her native country.

But until today, when MailOnline broke news of the scandal to a number of her friends who had not read about it, her friends and neighbours had regarded her as just one of the mothers who were bound together by their children attending the same school in New South Wales.

'The fact that never boasted or talked about it to any of us to my knowledge lends credibility to what she went through in my estimation,' said Kate Kirton who formed a close friendship with Ms Roberts because each of their three children went to the same school and were the same ages - eight, six and three.

Virginia Roberts said she was recruited as Epstein's sex slave when she was just 15 and paid $200 a time for an 'erotic massage' for him and his friends.

Now a married mother of three living in Australia, Virginia alleged that her services were offered to a number of politicians, businessmen and international statesmen.

She also met Prince Andrew. The first time was at the London house of Ghislaine Maxwell, daughter of the disgraced former media tycoon Robert Maxwell.

The second time was at Epstein's grand New York townhouse and the third on Epstein's private Caribbean island.

It was reported that she was flown across the world to be introduced to the Prince. On one of those occasions Virginia Roberts was subsequently paid $15,000 (£9,400).

One picture, said to have been taken by Epstein during Andrew's first encounter with the girl in March 2001 shows the Prince with his arm around her waist.

Describing what happened she said Epstein invited her to accompany him on a six-week trip in 2001.

They flew to Paris, then Spain, then Tangier and finally, they went to London.

'After we landed, we drove straight to Ghislaine's Maxwell's house' and 'was given a small upstairs bedroom,' Virginia said.

'She said I needed to be 'smiley' and bubbly because he was the Queen's son.

'Ghislaine and I went to Burberry, where she bought me a £5,000 bag, and to a few other designer stores where we bought a couple of dresses, a pair of embroidered jeans and a pink singlet, perfume and make-up,' she said.

'We got back to Ghislaine's house at around 4pm and I ran straight upstairs to shower and dress.

'When I went downstairs, Ghislaine and Jeffrey were in the lounge. There was a knock at the door. Ghislaine led Andrew in and we kissed each other on the cheek.

'Ghislaine served tea from a porcelain pot and biscuits. She knew Sarah Ferguson and they talked fondly about Andrew's daughters.

'Then Ghislaine asked Andrew how old he thought I was and he guessed 17'.

The four of them went out to dinner and on to Tramp nightclub where, she says, Andrew danced with her.

'After about an hour-and-a-half, we drove back to Ghislaine's. All of us went upstairs and I asked Jeffrey to snap a picture of me with the Prince. I wanted something to show my Mom. Ghislaine and Jeffrey left us after that, and later Andrew left'.

'She was probably the most open, friendly person you could care to meet.

But there was that moment when, in a passing conversation on a school day, Ms Roberts mentioned she had started writing a book.

The high probability that Ms Roberts is writing her disturbing life story will come as bad news for Buckingham Palace - should details of her alleged encounters with the Duke of York go into print.

Buckingham Palace has strenuously denied that Prince Andrew was involved illegally with Ms Roberts but in Australia she still has friends who believe her story.

Until she and her husband Robert, who works on the fringe of the clothing industry, moved to Florida with their children more than a year ago, they lived in a bungalow-style home close the sea in New South Wales.

That house is now occupied by Honor Symes , who told Mail Online today that she considers Miss Roberts as being a 'totally believable' mother who would have no cause to make up stories.

The house was actually purchased from Miss Roberts by Ms Symes' sister, who then sold it to her own sister.

Last night her father said Prince Andrew should be prosecuted if the claims were true.

Sky Roberts, 58, also claimed his daughter Virginia had been introduced to the Queen while visiting London with billionaire financier Jeffrey Epstein.

The sexual allegations were robustly denied by Buckingham Palace in an unprecedented three public statements, which describe them as ‘false and without foundation’.

There were also questions last night over the extraordinary legal deal that it is thought to have resulted in Prince Andrew – as well as other associates of Epstein – having immunity from any future prosecution.

According to a former Florida state attorney, the controversial deal was struck amid an astonishing and aggressive campaign by Epstein’s lawyers to defend their client against claims of depraved activities.

The deal meant Epstein – who was suspected for decades of paying for sex with dozens of under-age girls – was only ever convicted and jailed for 18 months on a single charge of soliciting paid sex with minors in 2008.

Documents filed at a court in Florida further allege that Prince Andrew was among those who made ‘efforts’ to secure the paedophile a favourable deal.

Andrew has spent the past week holidaying in the upmarket Swiss ski resort of Verbier with his ex-wife, Sarah Ferguson, their daughter, Princess Eugenie, and pals including Prince Harry’s ex-girlfriend, Cressida Bonas.

The prince, who is a keen skier, did not leave the chalet for the last two days of his holiday after the scandal broke.

Pursing his lips pensively yesterday, Prince Andrew walked to his car in full view of waiting photographers, followed a few minutes later by Eugenie, to ensure they were not in the same picture.

Andrew has no immediate public engagements in his diary but the Mail understands that he still plans to fly to Davos in Switzerland for the World Economic Forum on January 21. Sources say he will host a reception there for foreign ministers on behalf of the British Government as part of a ‘business as usual’ strategy.

Prince Andrew was staying in an opulent £22,000-a-week chalet at the exclusive Swiss ski resort of Verbier when the sex scandal broke.

The Duke of York was joined by his former wife Sarah Ferguson, their younger daughter Eugenie and Prince Harry’s ex-girlfriend Cressida Bonas for the luxurious jaunt.

Located in one of the most exclusive and remote parts of Verbier, it boasts seven bedrooms, its own heated indoor swimming pool with an opulent entertaining area and a sauna.

The Duke has used the chalet to host his own birthday parties in previous years and it is also the location where Prince Harry romanced Cressida.

The 54-year-old Duke of York is understood to have paid for the hire of the chalet out of his own private fortune.

Looking pensive and deep in thought, he left the chalet yesterday afternoon and was driven to a nearby airport where he boarded a private plane back to Britain with Eugenie, 24, and her boyfriend Jack Brooksbank.

In February 2013 Prince Harry was spotted hugging Cressida on the nearby ski slopes and the pair are understood to have shared a room at the chalet.

Harry splashed out £300 on a pair of designer snow boots for Cressida during that trip.

The Canadian-made Manitobah Mukluks Aboriginal grey boots are made from suede and rabbit fur and lined with sheepskin shearling.

And although the pair have since split, Cressida was invited back this time because she remains a close friend of Eugenie’s.

During Prince Andrew's most-recent stay, the royals were guarded by five protection officers – funded by taxpayers – who regularly drove them to the ski lifts and to restaurants.

The grand, old-fashioned wooden chalet hired by the Queen’s son boasts an extensive terrace area with stunning views of the Swiss Alps.

The master bedroom has its own en-suite bathroom and is draped in fur throws. It also boasts a sumptuous living room, littered with antiques and artworks, in which a roaring fire is lit each afternoon to welcome guests home from a hard afternoon on the slopes.

The chalet also has its own ski changing room so visitors can ski from the slopes to the privacy of their own home, without mixing with hoi polloi.

The piece de resistance, however, has to be its 650 foot square pool room with floor to ceiling windows offering unrivalled views out over the mountains.

This stunning room has its own bar where the royals have held several lively house parties on previous visits.

In the same year Sarah Ferguson lost more than two stone during a 12-week stay at the chalet.

The Duchess of York showed off a svelte figure after embarking on a relentless regime with her personal trainer Josh Salzmann.

The 55-year-old stuck to a strict diet of blended foods and intensive workouts, including daily running and mountain hikes.

The Duchess is understood to have stayed behind at the chalet after Andrew and Eugenie left yesterday.

Like her former husband, she too has kept a low profile since the underage sex scandal broke on Friday.
